In InterCompany, Part we have IUM is MCS (Our Defined UOM) and PUM is PCS. PO also made with OurQty in MCS and Supplier Qty in PCS. But when its come in Incomming PO Suggestion in another Company, IUM is coming in PCS due to which its giving Invalid Error.
Check the UOMs for the part in both companies (part entry). Also, have a look at customer price lists for the seller company. You may have entries there with the incorrect UOM. Same for the supplier price list on the other side.
Yea. I checked. In both companies Part UOM is same. Also, there is no Price List exists for this both Part. in both companies. Is there any other reason why UOM gets changes.
I think I’ve seen this recently when I was messing around with Part UOM Conversion in our Pilot. I would try different parts and POs but your best bet is Epicor support I think.
